Give each of the Sue blocks a border by adding 4 triangles, creating Squares on Point. Then each of your squares is much bigger. Use various colors, either solid pastels, or pastel tone-on-tone to play up the wonderful antique colors without dominating any of them. For example frame a Blue dressed Sue in a paler blue frame. Then lay them out and arrange them to your liking. Make a Triple Irish Chain putting the Vintage fabrics between two harmonious colors, like pink and lilac, or light green and light teal. See how it works, a dark and light grey might be just wonderful.
